The more sizeable situation with ventilation-produced patterns is if the compartment fire is ventilation-managed. Throughout this section in the compartment fire, there are actually ample UHCs produced, but absence ample oxygen for combustion. The burning in the course of air flow-controlled problems is commonly times detached from a fuel merchandise (i.e. wood chair) plus the pyrolyzates (unburned gasoline) will burn in places around ventilation openings and alongside airflow paths when enough oxygen for combustion exists (Custer and Wright 1984; Shanley et al.
